For the purpose of this chapter, buildings shall be classified by groups in respect to the occupancy or use, the fire hazard and the number and physical condition of the occupants, as follows:
A. 
Group A: Business. Buildings in which the primary or intended occupancy or use is the transaction of administrative business, civic or professional service and where the handling of goods, wares or merchandise, in limited quantities, is incidental to the primary occupancy or use. Newsstands, lunch counters, barbershops, beauty parlors and similar service facilities are considered as incidental occupancies or uses.
B. 
Group B: Mercantile. Buildings in which the primary or intended occupancy or use is the display and sale to the public of goods, wares or merchandise.
C. 
Group C: Industrial. Buildings in which the primary or intended occupancy or use is the manufacture or processing of products of all kinds, including operations such as making, altering, assembling, bottling, canning, finishing, handling, mixing, packaging, repairing, cleaning, laundering and similar operations.
D. 
Group D: Storage. Buildings in which the primary or intended occupancy or use is the storage of or shelter for goods, merchandise, products, vehicles or animals.
E. 
Group E: Public Assembly. Buildings in which the primary or intended occupancy or use is the assembly for amusement, athletic, civic, dining, educational, entertainment, patriotic, political, recreational, religious, social, sports or similar purposes, as defined in Chapter 66, § 66-1, of this Code.
F. 
Group F: Institutional. Buildings in which the primary or intended use is for persons domiciled or detained under supervision for reason, including but not limited to age, illness, physical or mental handicap.
G. 
Group G: Multiple Residential (including Condominium*). Buildings or space occupied by three or more dwelling units with one or more roomers or lodgers, or a one-family dwelling with three or more roomers or lodgers, used for shelter and sleeping accommodations on a day-to-day, week-to-week, month-to-month or longer basis.
[Amended 10-24-1983 by L.L. No. 2-1983]
*CONDOMINIUM
An arrangement under which a tenant in an apartment building holds full title to his unit and joint ownership in the common grounds.
H. 
Group H: Mixed Occupancies. In case two or more classes of occupancy occur in the same building or structure, so intermingled that separate safeguards are impractical, sprinkler protection shall meet the requirements of the most hazardous occupancy.
FIRE AREA
The floor area of a story of a building or structure within exterior walls, party walls, fire walls, or a combination thereof (NFPA: National Fire Protection Association).
A. 
A full automatic sprinkler system shall be provided in the following buildings:
(1) 
Group A, where the fire area exceeds 7,500 square feet or at buildings more than three stories high.
(2) 
Group B, where the fire area exceeds 5,000 square feet or at buildings more than one story high or in an enclosed mall.
(3) 
Groups C and D, where the fire area is more than 1,000 square feet or the building is more than one story high.
(4) 
Groups E and F shall be fully sprinklered in all areas.
(5) 
Group G. Sprinklers shall be installed in all hallways, stairways, storage rooms, refuse rooms, compactor shafts, maintenance rooms and laundry rooms.
B. 
Groups A, B, C, D and G. All basement areas used for garages or places of public assembly, as defined in Chapter 66, § 66-1, of this Code, shall be fully sprinklered, except open parking structures and areas specifically for cold storage and refrigeration.
A. 
New construction. This chapter shall apply to all new construction within the Village for which a building permit is required and where the building permit is issued subsequent to the effective date of this chapter.
B. 
Existing buildings. The provisions of this chapter shall apply to existing buildings in the following circumstances:
(1) 
When alterations or extensions requiring a permit involve 50% or more of the total size of the fire area of a space or building. The entire building shall be made to comply with the requirements of this chapter.
(2) 
If the alteration is one that requires a permit and is less than 50% of the space or building but results in a change in the occupancy group classification of the space or building, then the entire space or building shall be made to comply with the requirements of this chapter.
A. 
All sprinkler systems shall be installed, operated and maintained in accordance with current National Fire Protection Association standard for the installation of sprinkler systems and current National Fire Protection Association standard for care and maintenance of sprinkler systems.
B. 
Sprinkler systems shall be connected to an approved alarm-receiving facility for transmittal to the Fire Department.
C. 
All sprinklers shall be of the automatic type.
D. 
Sprinkler systems shall, upon actuation by heat produced by fire, automatically distribute water upon the fire in sufficient quantities either to extinguish it entirely or confine it without spread.
E. 
The component parts of sprinkler systems shall be designed, constructed and assembled so as to function as a unified sprinkler system or as part of a combined standpipe and sprinkler system. When hose connections are provided for Fire Department use, they shall have a two-and-one-half-inch valve outlet.
F. 
Connection to a sprinkler system for other than a sprinkler or standpipe use is prohibited.
G. 
Open-type sprinklers shall be provided with controls that will furnish water simultaneously to all the outlets protecting a given area.
H. 
Sprinklers connected to a potable water supply system shall be designed and installed so that they will not cause pollution.
I. 
Sprinkler installations in high-hazard occupancies, and in locations where the accumulation of water from sprinklers may be a potential hazard, shall be provided with drains for the removal of discharged water.
J. 
Sprinkler system mains, valves, risers and branches shall be protected from damage by fire. Such sprinkler piping which is not installed underground or is not enclosed in fire-resistive construction shall be protected by sprinkling the area in which it is located.
K. 
Piping shall be connected so that water from any designated source of supply can flow to any one or combination of risers to deliver its full rated capacity without excessive friction loss.
A. 
Sprinkler systems shall have at least one approved automatic source of water supply of adequate pressure, capacity and reliability.
B. 
Water pressure at the highest sprinkler shall be at least 15 pounds per square inch gauge for a pipe-schedule-designed system or seven pounds per square inch gauge for a hydraulically designed system, when an amount of water is discharged which is equivalent to the flow from the probably maximum number of sprinkler heads that may operate during a fire.
C. 
Water supply shall be sufficient to maintain an acceptable flow for a minimum period as defined by NFPA standards.
D. 
A connection through which the Fire Department can pump water into the sprinkler system will be provided as an auxiliary source of supply. Hose coupling threads shall conform to Fire Department threads.
E. 
When connection to a reliable public water supply can furnish at the highest sprinkler a pressure of at least five pounds per square inch gauge, the balance of the required pressure may be supplied by an automatic pump. Such pump shall be designed and installed for fire service, shall be protected against possible interruption of service by fire and shall be under constant electrical supervision with connection to transmit signals to an approved central station to receive the signals and take proper action.
F. 
Sprinkler systems of adjacent buildings may be connected from a common source of water supply, provided that such buildings are designed to remain permanently under a single ownership and provided that the source is of sufficient capacity for the largest sprinkler system within any one building.
A. 
Sprinkler heads shall be located and arranged to spray all parts of the area to be protected, including closets and alcoves.
B. 
In locations where ceiling temperatures up to 100º F. prevail, the temperature at which sprinkler heads operate to discharge water shall be from 135º to 170º F.
C. 
In locations such as furnace, boiler and laundry rooms where ceiling temperatures are over 100º F. but do not exceed 150º F., the temperature at which sprinkler heads operate to discharge water shall be from 175º to 225º F.
D. 
Sprinkler heads operating at temperatures exceeding 225º F. shall be used only for locations where unusually high temperatures prevail.
E. 
Sprinkler heads shall be located so that there is no interference with the effective distribution of water.
F. 
Luminous ceilings located above or below sprinkler heads shall be installed in conformity with Sections C 403-3h and C 403-31.
All local laws, ordinances or parts thereof inconsistent with the provisions of this chapter are hereby repealed; provided, however, that such repeal shall be only to the extent of such inconsistency, and in all other respects this chapter shall be cumulative of other local laws and/or ordinances regulating and governing the subject matter covered by this chapter.
If any section or provision or parts thereof in this chapter shall be adjudged invalid or unconstitutional, such invalidity or unconstitutionality shall not affect the validity of this chapter as a whole or any other section or provision thereof.
This chapter shall take effect immediately.
